24 alternatives to ElectricSQL, Postgres to SQLite active-active sync for local-first apps

Hi HN, James, Valter, Sam and the team from ElectricSQL here. We're really excited to be sharing ElectricSQL with you today. It's an open source, local-first sync layer that can be used to build reactive, realtime, offline-capable apps directly on Postgres with two way active-active sync to SQLite (including with WASM in the browser). Electric comprises a sync layer (built with Elixir) placed in front of your Postgres database and a type safe client that allows you to bidirectionally sync data from your Postgres to local SQLite databases. This sync is CRDT-based, resilient to conflicting…

ElectricSQL is an open source sync layer that enables bidirectional data synchronization between Postgres databases and local SQLite instances, including in web browsers via WebAssembly. Built with Elixir, it uses… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

   Bi-directional sync between Postgres and SQLite▲356

   Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is…

   Replicate App-Embedded DuckDBs into PostgreSQL with SyncLite OSS▲73

   Hi HN, We have been building SyncLite, an open-source platform to simplify offline-first application development. If your application uses SQLite or DuckDB, SyncLite lets it continue using the local database as usual while synchronization happens in the background. For SQL-based applications, SyncLite records transactions into transactionally consistent .sqlog files using SQLite as an open replication format. A background consolidator replays those transactions, derives row-level CDC and schema changes, and applies them transactionally to destination databases like PostgreSQL. The same…

   Multiplayer Demo Built with Elixir▲221

   Hey HN, I’m an engineer at Supabase [0] and one of the creators of this demo. My team and I have been working hard to bring developers the next version of Supabase Realtime. The current version of Realtime [1] is a Change Data Capture (CDC) server for a PostgreSQL database that broadcasts changes via WebSockets to authorized subscribers. It’s written in Elixir&#x2F;Phoenix. The server utilizes PostgreSQL’s logical replication functionality, which writes database changes to Write-Ahead Logging (WAL) segment files, and a replication slot, responsible for managing and retaining WAL files.…

   Embed an SQLite database in your PostgreSQL table▲180

   pglite-fusion is a PostgreSQL extension that allows you to embed SQLite databases into your PostgreSQL tables by enabling the creation of columns with the `SQLITE` type. This means every row in the table can have an embedded SQLite database. In addition to the PostgreSQL `SQLITE` type, pglite-fusion provides the `query_sqlite`` function for querying SQLite databases and the `execute_sqlite` function for updating them. Additional functions are listed in the project’s README. The pglite-fusion extension is written in Rust using the pgrx framework [1]. ---- Implementation Details The PostgreSQL…

   Hatchet – Open-source distributed task queue▲578

   Hello HN, we're Gabe and Alexander from Hatchet (https:&#x2F;&#x2F;hatchet.run), we're working on an open-source, distributed task queue. It's an alternative to tools like Celery for Python and BullMQ for Node.js, primarily focused on reliability and observability. It uses Postgres for the underlying queue. Why build another managed queue? We wanted to build something with the benefits of full transactional enqueueing - particularly for dependent, DAG-style execution - and felt strongly that Postgres solves for 99.9% of queueing use-cases better than most alternatives (Celery uses Redis or…

   PGlite – in-browser WASM Postgres with pgvector and live sync▲509

   Hey, Sam and the team from ElectricSQL here. PGlite is a WASM Postgres build packaged into a TypeScript&#x2F;JavaScript client library, that enables you to run Postgres in the browser, Node.js and Bun, with no need to install any other dependencies. It's 3mb Gzipped, now has support for many Postgres extensions, including pgvector, and it has a reactive "live query" API. It's also fast, with CRUD style queries executing in under 0.3 ms, and larger, multi-row select queries occurring within a fraction of a single frame. PGlite started as an experimental project we shared on X, and the…

    Hatchet v1 – A task orchestration platform built on Postgres▲240

    Hey HN - this is Alexander from Hatchet. We’re building an open-source platform for managing background tasks, using Postgres as the underlying database. Just over a year ago, we launched Hatchet as a distributed task queue built on top of Postgres with a 100% MIT license (https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39643136). The feedback and response we got from the HN community was overwhelming. In the first month after launching, we processed about 20k tasks on the platform — today, we’re processing over 20k tasks per minute (>1 billion per month). Scaling up this quickly was…

    We just launched Outerbase Studio, the open-source version of our core database offering. It works in your browser or as a desktop app and supports MySQL, PostgreSQL, and SQLite. What it does: • Connects to MySQL, PostgreSQL, and SQLite databases. • Spin up local databases directly through the UI, even if you don’t have one running. • Manage and query your data in a lightweight, intuitive interface. • Completely open source. Why we built it: We wanted to share the core Outerbase experience with the developer community as a free, open-source tool. It’s simple, fast, and removes the barriers…

    This is an experimental extension for CRDTs, pg_crdt: GitHub repo[0]. It supports Yjs&#x2F;Yrs and Automerge. The linked blog post [1] describes how we're thinking about this extension in a Supabase context. I want to emphasise this part: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync&#x2F;support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."

    SnapQL – Desktop app to query Postgres with AI▲104

    SnapQL is an open-source desktop app (built with Electron) that lets you query your Postgres database using natural language. It’s schema-aware, so you don’t need to copy-paste your schema or write complex SQL by hand. Everything runs locally — your OpenAI API key, your data, and your queries — so it's secure and private. Just connect your DB, describe what you want, and SnapQL writes and runs the SQL for you.

    PG-Capture – a better way to sync Postgres with Algolia (or Elastic)▲56

    Hello HN! Keeping Elasticsearch or Algolia in sync with Postgres is a pain when your data spans multiple tables. Traditional CDC tools like Debezium capture table-level events but don’t help when you need to index a full entity composed of related records. That's why I built PG-Capture. PG-Capture lets you define a schema as complex as you need, aggregate table-level events, and reconstruct structured objects spanning multiple tables. It then publishes them as meaningful domain-level events to any queue (RabbitMQ, SQS, etc.). PG-Capture does NOT replace Debezium, it works on top of it (or…

    Peerdb Streams – Simple, native Postgres change data capture▲177

    Hello HN, I am Sai Srirampur, one of the Co-founders of PeerDB. (https:&#x2F;&#x2F;github.com&#x2F;PeerDB-io&#x2F;peerdb). We spent the past 7 months building a solid experience to replicate data from Postgres to data warehouses. Now we're expanding to queues. PeerDB Streams provides a simple and native way to replicate changes as they happen in Postgres to Queues (Kafka, Redpanda, Google PubSub, etc). We use Postgres logical decoding to enable Change Data Capture (CDC). Blog post here: https:&#x2F;&#x2F;blog.peerdb.io&#x2F;peerdb-streams-simple-native-postgres.... 10-min quickstart here:…
